Passing vectors as PMT

GNU Radio

Hi,

I’m passing the content of a std::vector as a pmt. Question is, do I do
it as a blob, or do I set up a pmt vector? The latter seems safer, and
easier accessible in Python, but it’s also more complicated (as I can’t
create pmt vectors directly from std::vectors).

Has anyone done this, and have any suggestions?

try make_blob(&vec.front(), num_bytes);

It makes a copy of whatever pointer you pass into it.
